Application filed July 6,

To all whom it may concern: Be it known that I, EDWARD A. Owens, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Stencil Printing Machines, of which the following is a specification.

This invention relates to a printing mam chine and especially to a multi-color printing machine in which the colors are selected, applied to the surface of a stencil, and transferred therethrough one by one.

Heretofore in Patent No. 1,254,764, entitled Method of delineating or reproducing pictures and designs, issued Jan. 29, 1918, and in my co-pending applications April 16, 1919, Serial No. 290,374, and April 14, 1920, Serial No. 373,828, I have described a method of printing and reproducing multicolor pictures, designs, etc., which consists in tracing or otherwise outlining a picture on a fabric screen or similar partially penetrable material; masking certain areas as outlined to form a stencil on the screen, and applying and transferring the colors one by one through the unmasked areas.

In actual operation when employing the method outlined, hand operation has been entirely resorted to, that is the paint or other color employed is poured on the screen or stencil and then spread and transferred by a hand-operated squeegee. Hand operation is strenuous work. It requires that a man use heavy pressure on the squeegee to force the thick paint through the screen and as this operation is ordinaril repeated several thousand times during a ays work, it can readily be imagined that the work is, comparatively speaking, exhausting. General observation has shown that the quality of the work decreases as the operator tires, that is uniformity of product is not obtained, the output decreases and the paint employed is either wasted or disadvantageously employed. I

One of the-objects of the present invention is to generally improve and simplify the operation of applying and transferrlng the paint or other material employed; to greatly increase the output; to materially increase the uniformity and quality of the work; to economize, first, by reducing the quantity of paint or other coloring matter used; second, to reduce the number of spoils; third to 1921. Serial No. 482,678.

lessen the wear and tear of the screen or stencil, and finally to lessen the labor and skill otherwise required.

Another object of the invention, and one more specifically stated, is to provide a machine, comprising a table for the reception of the stock or material to be printed; a stencil supporting frame, means for automatically raising and lowering the frame, and means for automatically applying and transferring colors through the stencil.

Another object of the invention is to provide means whereby a predetermined register may be easily and quickly obtained between the stencil and the stock to be printed; and further to provide means cooperating there with for automatically ejecting the stock when printed.

Another object of the invention is to provide means whereby the screen so porting frame may be longitudinally and laterally adjusted with relation to the table and the lifting frame.

Further objects will hereinafter appear.

The invention consists of the arts and the construction, combination an arran ement of parts as hereinafter more fully escribed and. claimed, having reference to the accompanying drawings, in which- Fig. 1 is a side elevation of the machine.

Fig. 2 is a front end View of the same.

Fig. 3 is a plan View of the machine.

Fig. 4 is an enlarged longitudinal cross section of the lifting frame, the stencil supporting frame carried thereby and the squeegee.

Fig. 5 is a transverse cross section of the lifting frame and the stencil supportin the frame carried thereby, said view also s owing the squeegee and its supporting frame in end view.

. Referring to the drawings in detail, A indicates a main frame of suitable construction upon which'is supported a table 2. Disposed within the frame and journalled cross: wise thereof,is a main cam shaft 3, a secondary cam shaft 4:, a rocker shaft 5, and a second rocker shaft 6. J ournalled lengthwise ofthe frame is a main drive shaft 7 and an auxiliary rocker shaft 8. The main drive shaft may be connected with an electfic motor or any other suitable driving mechanism not here shown. Secured on the drive shaft is a worm pinion 9, andintermeshing therewith is a worm gear 10. which is keyed or otherwise secured on the main cam shaft 3. Continuous rotary movement is in this manner transmitted to the main cam shaft and a similar movement is transmitted to"- the secondary cam shaft 4 b means of a beveled ear drive indicated at 11 and 12. Disposed on top of the table is a lifting frame 14. Supported therein is a stencil frame 15, and also supported thereby is a pair of longitudinally extending channel shaped track members 16. between which is is disposed at squeegee supporting frame generally indicated at 17. The main frame 14 is intermittently raised and lowered with relation to the table to permit insertion and automatic ejection of the stock to be printed. The entire frame is lifted by means of a tilting movement: this being accomplished by securing the rear end of the frame to a cross shaft 18. which is journalled at the rear end of the table 2. Securedon the cross shaft is a crank arm 19, and adapted to impart an intermittent rocking movement thereto, at predetermined time intervals, is a link 20, and a rocker arm 21 pivotally secured on the main frame A, as at 23. Adapted to impart an intermittent rocking movement to the arm 21, is a cam 24. This cam is secured on the main shaft 3 and it has ashape such as generally indicated by dotted lines at 24 in Fig. 1. A roller on the lower end of the rocker arm 21 engages one side of the cam. This side of the cam imparts a rocking movement to raise or tilt the frame 14 with relation to the shaft 18 and as the frame drops by gravity when released by the cam, it is obvious that the other side of the cam merely controls or retards the lowering speed of the frame. A second cam 25 secured on the shaft 3 engages a roller.

26 secured at the outer end of a crank arm 27. This arm is secured on the rocker shaft 6, which shaft also carries a pair of rocker arms 28, disposed one on each side of the, frame. (See Figs. 1, 2 and 3.) The up er ends of the arms are slotted as at 29 and a cross head 30 is slidably mounted in the slotted portion of each arm and so connected with the squeegee frame 17 that a reciprocal movement is transmitted thereto between the channel shaped guide tracks 16' when engagement is made between the cam '25 and the crank arm carrying the roller 26. The positioning of the cams 24 and 25 is such that a complete reciprocal movement will be imparted to the squeegee frame when the main frame 14 is lowered or supported by the table. The squeegee frame is other wise disposed near the rear end of the frame 14 and remains stationary at this point when the frame 14 is being raised and lowered by means of the cam 24. In fact the position of the cam25 as shown in Fig. 1, is such that thesqueegee frame has just reached its extreme forward position and is ready to be retracted or returned to its normal stationary position at the rear end of the frame 14. ()ne-half a revolution of shaft 3 is required to impart a reciprocal movement to the squeegee frame through the medium of the arms 28, while during the other one-half revolution of the shaft, the squeegee and arms 28 remain stationary. It is during this rest period that the cam 24 engages the rocker arm 21 and that the tilting movement is imparted to the lifting frame 14, such tilting movement being permitted as the slight vertical movement imparted to the rear end of the lifting frame is taken care of by the slots 29 and the cross heads slidably mounted therein.

The main cam shaft serves three functions, first that of raising and lowering the lifting frame 14; secondly that of imparting one reciprocal movement to the squeegee frame, one during each revolution; and third, that of transmitting power to the secondary cam shaft 4 through means of the beveled gears indicated at 11 and 12. The secondary cam shaft, as previously stated, is continuously rotated in unison with the main cam shaft 3. It carries three sets of cams indicated at 31, 32 and The cam 33 actuates the mechanism whereby the printed stock is automatically ejected after each printing operation. It will therefore be referred to as the ejecting cam. This cam is nothing more or less than a collar such as shown in Fig. 2, which is secured to the shaft 4. One face of the collar is provided with an angular beveled edge 34 in which is formed a recess 35. One side of the recess is parallel with the longitudinalaxis of the shaft 4 as shown at 36, while the other side of the recess is gradually inclined and forms a part of the angular face 34. Engaging the working face of the cam is a crank arm 37 which is secured on a shaft 38 longitudinally disposed with relation to the main frame and journalled therein. Secured on the shaft are two knock-out fingers 39 and connected with the crank arm 37 is an ejecting spring 40.- During the rotation of shaft 4 and the ejector cam 33 secured thereto, it is obvious that the end of the crank arm 38 will normally engage the angular face 34 formed on the cam and as the direct-ionof rotation is that indicated by arrow (1, see

Fig. 2. it is obvious that the drop in the cam ends indicated at 35 will be reached and that the crank arm will suddenly be released and thus instantly retracted by the spring 40. The shaft 38 is thus rocked and the knock-out fingers 39 carried thereby will engage one side of the stock and strike the same with such force that the stock is ejected. This'of course takes place the moment the stock has been printed and the lifting frame 14 raised. Continued movement ofthe cam 33 will cause the inclined shafts b face 36 to engage the crank arm and the shaft 38 willagain be rocked and the fingers retracted in readiness forthe next knockout or ejecting operation.

The cam indicated at 31 is employed for the purpose of transmitting a rocking movement to the rocker shaft 5. i This is accomplished by hanging a link 41 on the shaft 4,

that is the link is slotted as at 42 and hangs thus finally transmitted to the shaft 5. This shaft performs two functions, first that of transmitting a vertical reciprocal movement by a rod 47 to one of'the registering fingers projecting through the table and indicated at 45; and secondly that of transmitting a rocking movement to the rocker shaft 8; the transmission of movement from shaft 5 to 8 being accomplished by connecting the means of a pair of beveled gears 46, see ig. 2. The shaft 4 also imparts a reciprocal movement to a link 47; the link 47 being operated by means of a cam 32 on the shaft 4.

Before proceding further with the general description of the mechanism employed, it might be well to state that six registering fingers are employed for the purpose of positioning and securin the stock during the printing operation. 6m of the registering fingers is indicated at 45, and the remaining fingers at'49, 50, 51, 52 and 53. The

' fingers 49 and 50 are operated by one part of the mechanism hereinafter to be described; the finger 45 by the mechanism already described, and the fingers 51, 52 and 53 by another part of the mechanism to be hereinafter described. The finger 45 has a vertical movement to project or lower it with relation to the table surface and it also has a jogging and a gripping movement. The fingers 49 and 50 may be termed gripping and jogging fingers as they have both a vertical movement and a jogging movement, and the fingers 51, 52 and 53 may be termed gripping fingers as they only have a vertical movement. The mechanism operating the fingers 49 and 50 is partially actuated by the rocker shaft 8. This rocker shaft has two crank arms secured thereon which straddle vertically disposed rods 54; one of the fingers, 49, being secured on one rod and the other finger 50' on the other rod.

4 A rocking movement imparted to. the shaft 8 is transmitted through the crank arms to raise the rods 54 an the fingers49 and 50 carried thereby, and springs disposed at the lower ends of the rods indicated at 55, serve the function of lowering or retracting the same. The cam 32 secured on shaft 4 will, through the medium of link 47, and a sliding rod 48, transmit a rockin movement to a bell crank indicated at 56, see Fig. 3) and through a link 57 connected therewith a jogging or tilting movement is transmitted to the rods 54 and the fingers 49 and 50 as the opposite end of the link 57 is attached to a plate connecting the rods 54, as indicated at 58. In other words vertical movement is imparted to the fingers 49 and 50 by the shaft 8, and a jogging movement is transmitted from shaft 4 through the mechanism generally indicated at 33, 47, 48, 56, 57 and 58. The rod 48 has a collar 47 secured thereon and this serves the function of engaging the finger 45 and simultaneously imparting a jogging movement thereto. upper ends of the fingers 49, 50, 51, 52, 53 and 45, are hook shaped as shown at 59. They are therefore adapted to grip the edge of the card or stock to be printed and thereby secure it against vertical movement with The the lifting frame when this is raised as will hereinafter be described. The fingers 51, 52 and 53 are secured to a triangular shaped plate disposed below th'etable and indicated at 60. This plate is secured on the upper end of a rod 61, and this rod is actuated by means of a cam 62 secured on the link 20, that is a roller is secured on the rod 61 and this roller is engaged by the cam 62. A vertical raising movement is thus transmitted to the rod 61, the plate 60 and the fingers 51, 52 and 53 carried thereby, and a lowering or clamping movement witlr relation to the table is transmitted by means of a spring 63 interposed between the lower endof the rod and the main frame A, see Fig. 1.

The entire driving mechanism and the parts actuated thereby have now been described and a detail description of the squeegle iron as shown at 64, see Figs. 4 and 5.

The screen support-ing frame is preferably made of wood and is generally indicated at 65. It is also rectangular in shape and the lower face of the sides and the ends of the frame 65 are channeled to receive clamping strips 66. The screen employed is generally constructed of finely woven silk. The silk indicated at 67 is secured with relation tothe frame 65 by means of the clamping strips 66 and is in this manner tightly stretched and securely supported; the clamping strips being secured in any suitable manner, or as here shown by means of screws 68. One of the end sections of the frame 65, or that indicated at (39, in Fig. 4, is adjustable to permit the screen or Silk fabric (37 to be tightened lengthwise; the adjustment being obtained by means of a threaded ferrule and a screw 71. Again it is possible to obtain adjustment of the main frame 65 and the registering fingers 0n the table by means of combined adjusting and clamping screws indicated at 72. These screws secure the frame 65 within the lifting frame aiid they permithoth lateral and longitudinal adjustment as specified. The channel shaped tracks running longitudinally of the lifting frame. and disposed one on each side thereof. are secured in any suitable manner. They serve the function of supporting the squeegee frame and guiding the same during its reciprocal movement with relation to the stencil. This is accomplished in the following manner:

The squeegee consists of a pair of head members, see Figs. 4 and 5, generally indicated at 73. Journalled on each head member is a pair of spaced rollers 74 which en-'.

ter the channeled shaped tracks 16, thereby forming guides and supports for the heads 73. The heads 73 are connected by means of a pair of cross bars 75, said cross bars being secured to the heads by means of screw 76. The cross bars are interspaced as shown in Fig. 4, and disposed between the same is a pair of interspaced guide and supporting plates 77 and 78, between which is interposed a squeegee 79. Also interposed between the plates 77 and 78 is a top plate or bar 80, and engaging the same are a suitable number of adjusting screws 81, whereby vertical adjustment of the squeegee may be obtained; the screws 81 being carried by cross clips such as shown at 82. Vertical adjustment of the squeegee between the plates 77 and 7 8 is obtained by means of the screws 81 and the bar 80, and clamping of the squeegee to retain such adjustment is obtained by two or more clamping screws 83 carried by the cross bars 75. These screws engage the plates 77- and 78. thereby forcing them together and clamping the squeegee 79 between the same. Also supported by the cross bars is a paint receptacle 84. This receptacle consists of a piece of sheet iron or the. like bent to form a pair of end sections 85 and a rear section 86. There is no top or bottom for the receptacle. The squeegee forms the front of the receptacle, the rear section 86, the rear sidethereof, and the sections 85 the enclosures thereof. The ,paint deposited therein is however retained: first by the 'squeegee 79, secondly by a follower 87, and third by a pair of end Squeegees or liners shown at 88. The squeegee in reality consists of a paint reservoir or container, 2. distributing blade 87, and a squeegee blade 79. These several elements operate in unison and form an exceedingly important feature of the the paint'to [ill the pores of the screen to a uniform surface. The squeegee on the return stroke removes any excess that may have been deposited on the screen and s1- multaneously presses or forces the remaining paint-through the meshes or pores of the screen surface; this being accomplished with an even stroke and pressure that causes a uniform transfer and cleans the silk entirely of paint. The rounded edge of the squeegee 9 gives flexibility and decreases resistance when moving in one direction and causes removal of paint and the application of pressure during the return stroke. The supportin plates 77 and 78, together with the bar 80, permit the rubber squeegee to be adjusted to a fine degree, thus permit-.

ting the blade to engage-the screen or silk uniformly throughout 1ts'.length and at all 1 points.

Another nnportant feature is the provision of means for laterally and longitudinally adjusting the screen or stencil suporting frame with relation to the lifting mine. This is readily and quickly accomplished in the present instance by the adjusting screws indicated at 72 and is of importance as it permits absolute registry of the screen frame with relation to the card or stock secured between the registering fingers, for instance when changing colors or runs, etc..

Another important feature is the adjust- .ability of theendsections 69, that is any sag 0r stretch imparted to the silk fabric naturally takes place in the direction of movement of the squeegee, most of which slack may be readily taken up as the ferrule 70 and the adjusting screw 71 are provided. The grippers or registerin fingers, previously referred to, and particifiarly the hook portions formed thereon, are necessary to grip the card on the-table surface particularly during the time period when the lifting frame is being raised. Paint is a sticky viscous-body and has a'tendency to adhere and lift the cards. This action will materially slow up the machine as a whole if permitted, and might in some instances even smudge the stock. However this is entirely obviated and takencare of by the grippers 51, 52 and 53. He does not necessarily have to make engagement with the fingers 51, 52 and 53, as such engagement is taken care of by the jogging movement of the fingers 45, 49 and 50. Automatic, positive and uniform register is in this manner obtained and the speed and output can be materially increased as the effort and work of the operator is merely directed to 'inserting the stock.

Another important feature is the fact that the fingers 51, 52 and 53 are raised when a previously printed card is released for ejection, thus presenting high projections which are easily engaged when the cards are inserted. In fact even a curled card can be easily handled as it will not have the same tendency to slide over the fingers as where a low registering finger is employed. The fingers 45, 49 and 50 are of course retracted below the table surface during the releasing and ejecting operation as it would otherwise be difficult to feed in the stock and similarly eject the same.

In actual operation the stock to be printedis placed upon the surface of a table when the lifting frame assumes its elevated or tilted position; a registry between the stock and the stencil screen being quickly and automatically obtained as the operator merely moves the stockinto abutment with the finger 51. The fingers 49 and insure engagement of the stock with the finsqueegee.

gers 52 and 53, finger 45 simultaneously insures engagement with finger 51, and clamping of the stock takes place when the fingers are depressed or partially retractfi. The lifting frame is next lowered and a reciprocal movement is imparted to the s ueegee frame by means of the arms 28, while the lifting frame is in engagement with the table; the paint being first distributed over the screen or stencil, and secondly transferred therethrough by the pressure exerted through the medium of the The squeegee frame comes to a tern rary rest, the moment the return stro e has been completed and the lifting frame is then immediately raised. The fingers 45, 49 and 50 are then jogged back and retracted below the table surface; the fingers 51, 52. and 53 are simultaneously raised and the knock-out fingers are then released and will, due to the tension of the spring 40, move forward with a trigger-like movement. thus striking the stock now released with relation to the registering fingers with such force that it will be automatically ejected. The operator has. during this period, grasped the next section of stock to be inserted and is therefore ready to move it into approximate register with the fingers 51, 52 and 53, the moinent ejection has taken place. This cycle of operation is repeated and. repeated and fairly unskilled" labor or operators may be employed as,

practically speaki the only duty required is that of feeding t e stock.

If for any reason it happens that the operator may want to leave the lifting frame in raised position and secure the squeegee frame against reciprocal movement with relation thereto when assuming its rearmost position, it is accomplished by rocking a lever 90. This lever is pivotally mounted on the main frame A as indicated at 91. One end of the lever or that indicated at 92 is adapted to engage a notch 28 formed in the arms 28, thus securing the arms 28, the rocker shaft 6 and the crank arm 27 against forward movement as long as engagement is maintained between the projection 92 and the arms 28. The rocker arm 21 is similarly locked against rocking movement by sliding bar 93. This sliding bar is connected with the member 92 by means of a link 94. This link exerts a pull on the bar 93and moves it to a position where it will engage the rear side of. the rocker arm 21. thus securing it against return movement when the lifting frame has been tilted. The remainder of the mechanism will of course operate. but as the lifting frame and the squeegee remain stationary, it is of no consequence whether the grippers, etc., are operated or not. The operator may want to temporarily stop the main operating parts. for instance when more stock is required or when making temporary adjustments or otherwise. and it is obviously an advantage to be able to temporarily stop the main parts of the machine from operating as the top ofthe table 2 might-otherwise become smeared or flooded with paint.

From the foregoing description it can be seen that the entire operation of the mechanism is automatic, and that the operator has no other work to take care of than that of feeding the stock to the machine. The output should therefore be great and in actual practice will approximate fifty impressions or'transfers a minute. The speed may however be slightly varied as the skill of the feeder or operator increases. The quality of the work roduced is materially improved; the work is uniform in appearance and the amount of paint or color employed is materially decreased; spoils are practically eliminated; smeared or dirty work is, practically speaking, inexcusable, and the wear and tear of the screen or silk fabric employed is materially lessened as uniform pressure is always applied thereto.

While certain features of the present invention are more or less specifically illustrated, I wish it understood that various chan es in form and proportion may be resorted to within the scope of the appended claims, similarly that the materials and finish of the several parts employed may be are Hit?
